Yep, I choose the moves. But if you want a certain move on your pokémon (provided it learns the move legally), PM me and perhaps I'll give it to you if your IC post impresses me. Now over to..
Congratulations! You have recieved a Pichu lvl. 5
- Ice Fang
EDIT: You are allowed to evolve Pichu anytime you want, but a reasonable time should have elasped. You just can't raise his friendship level from 'ignored' to 'best pals' in a minute.
